The Meaning of Life, the Universe, and Everything.
I know there's an ore gen unification mod already. But for some reason I could never get it to work. The game always crashes while it's loading my mod pack. But simply what it does is it adds in it's own ore gen blocks for everything from copper to silver, quarts, slate, marble ect. Any duplicates of the same block that other mods add it. At the same time it suppresses ore gen from those other mods. And when the player mines the block this mod adds in. It will drop the most commonly ore used in the all of the games recipes.
